Yesterday after calling procharger to order a new air filter I found out for the first time that I need to change the oil every 6,000 miles in the system

. The problem is the dealer who I bought the car from never told me anything about this and I thought the procharger took oil from the engine.
So now 16,000 miles later and no oil change on my procharger, I am hoping by the time the new oil comes nothing would have went wrong inside of my procharger. Is there any way I can tell about if not changing the oil on my system messed anything up on the inside. Or am I just lucky that everything still seems to be working yet? Im just worried I might have worn the bearings down or something and am headed for a catastrophe

. I checked the dipstick on the system and it is completely covered in the blue oil so im guessing it still is full.
